Full-automatic door opening and closing device

Abstract

The invention relates to a full-automatic door opening and closing device. Obliquely upward sliding grooves are formed in supporting plates on the two sides of a frame, a lifting in-out unit is arranged on sliding rails and can move up and down, and a driving unit is in driving connection with the lifting in-out unit and can drive the lifting in-out unit to move up and down along the sliding rails; shafts are installed on fixing blocks on the two sides of a door plate of the automatic door, the shafts are sleeved with check ring bearings, bearing connecting pieces and second bearings, first bearings are arranged at outer ends of the bearing connecting pieces, and follow-up plates are installed on the bearing connecting pieces; a guide rail and a cylinder are mounted on a mounting plate of the lifting in-out unit, a sliding block is arranged on the guide rail, a piston rod of the cylinder is in driving connection with the sliding block, a sliding block plate is connected to the sliding block, a driving plate is fixed to a lower portion of the sliding block plate, and the cylinder can drive the sliding block plate and the driving plate to move left and right; an automatic door baffle used for limiting an overturning angle of the door plate is installed on the frame. The device is advantaged in that collision between doors when opening and closing the doors is avoided, a lifting in-out unit is small and exquisite in structure, and a large amount of space is saved on the premise that the use requirement is met.

Description

technical field [0001] The invention relates to a fully automatic door opening and closing device. Background technique [0002] At present, it is necessary to design an automatic mechanism for opening and closing the door for the automatic device to realize automatic feeding and retrieving, so as to save the cost of design, make the opening and closing of the door convenient and labor-saving, and not easy to damage. [0003] The Chinese patent No. 2019103030035 discloses a fully automatic door opening and closing device, which realizes the automatic operation of opening and closing the door of the aging device. The driving pallet on the lifting and exiting unit moves linearly along the guide rail under the drive of the cylinder, making The drive pallet enters or leaves along the X-axis direction, and its structure is complex, occupying the internal space of the equipment. Contents of the invention [0004] The purpose of the present invention is to overcome the deficienc...
